Trivia questions via the open Open Trivia Database (OpenTDB) — no key. The questions endpoint returns multiple-choice and true/false questions filtered by category, difficulty (easy, medium, hard) and type, each with the question text, the correct answer and the incorrect options; answers are decoded server-side to clean text. The categories endpoint lists all 24 trivia categories with their ids, and count returns a category's question-count breakdown by difficulty. A random endpoint pulls a single question with the same filters. Real trivia data straight from OpenTDB, fetched fresh — no key. 5 endpoints. Ideal for quiz and trivia games, pub-quiz generators, icebreakers, study apps and chatbot mini-games.

A ready-to-use trivia engine with more than 44,000 multiple-choice questions across 20 categories — animals, brain teasers, celebrities, entertainment, kids, general knowledge, geography, history, hobbies, humanities, literature, movies, music, people, religion, science & technology, sports, television, video games and world. Pull a random question or a batch (optionally filtered by category, with the answer hidden for gameplay and the options shuffled), fetch a specific question by id, verify a submitted answer, search questions by keyword, and list every category with its question count. Every endpoint accepts input via the query string or the request body and returns lean JSON. Pure server-side data (no third-party upstream), so responses are instant and always available. Ideal for quiz and trivia games, pub-quiz and party apps, learning tools, chatbots and Discord/Slack bots.
